Módulo de conversión de potencia de descenso DC-DC de 9V/12V/24V/36V a 5V con doble USB, 3A

Quite nice, will handle 2 amps and more (total), but needs extra cooling. I glued little radiator to dissapate more heat. I wouldn't risk going for full load 24/7, could overheat. Other than that doing grat job charging phones, tablets, etc. Single socket will give you 1.5 amps max because theres no resistor coding. Add some resistors and you can enable apple type output for example.
Tengo mi artículo y la carne las especificaciones, pero es un poco triste. El mío vino sin el puerto USB. (¿Alguna vez has intentado conseguir que el artículo sea reemplazado con BanggoOD. La vida es demasiado corta). Así que voy a chupar para arriba. El heno funciona pero a 2 amperios parece muy bajo en potencia. Es más como 0.5 amperios. Sería bueno saber quién más tiene problema con este artículo. Tristemente, esta revisión, nunca será PUBLICADO porque BANGGOOD solo publica el BIEN!
I made my own "power bank" with low voltage alarm for my LiPo batteries. See pictures.
I'm mounting this in an outlet for my battery backup system. Our power goes out a lot. I wired my house for 12 volts and this will make it easy to charge my phone and other things. I added a switch so it doesnt use power when it's not being used to charge.
muy buena compra
I ordered a bunch of these to install in cars. They are based off LM2596, which is rated for 5V 3A output. I think the price is great and function is perfect. Happy with the order.
good value for money Very useful for diy projects.
Good value for money. Not yet tested
Seems to deliver stable 5V (approx) power under a wide range of input conditions. However, the efficiency is not particularly high at low currents, as would be expected. Attached is a table of efficiency calculations using my non-calibrated equipment. No load current is 5mA which is a bit high for my liking. John from Ontario, Canada
Vino empaquetado de una manera sencilla pero llegó intacto y funcionando bien, solo probé con 12v. Lo probaré con fuentes de otros voltajes para ver si sigue cargando bien. Cargue rápido. Satisfecho hasta ahora.
